EDGE SETT'ER AND BURNISHER. I

Specification of Letters Patent.

Patented Dec. 6, 1921.

Application filed November 12, 1917. Serial No. 201,521.

To all 10720712275 may concern Be it known that I, OTIS R. ANenLL, acitizen of the United States, residing at Haverhill, in the county ofEssex and State of Massachusetts, have invented certain new and usefulImprovements in Edge Setters and Burnishers, of which the following is aspecification, reference being had therein to the accompanying drawings.7

This invention relates to machines for setting and burnishing theedgesof shoe soles and. more particularly to means for supporting and forreciprocating the operating tool.

In machines of the above type as at present constructed and in whichcranks 01'' eecentrics have been employed for reciprocating the tools,much annoyance has been caused by reason of the excessive vibrationproduced, resulting in disagreeable noise and rapid wear of parts. It isan object of the present invention to so construct a machine of theabove type as to eliminate all unnecessary machine parts and at the sametime to reduce undesirable vibration to a minimum.

It is a further object of the invention to provide in an edge settingmachine a tool holder constructed to simultaneously hold a plurality oftools and adapted to be sewntrolled as to present either of said toolsin working position at the will of the operator.

Other and additional objects and advantages of the present inventiontogether with desirable details of construction and improved combinationof'parts will be hereinafter described and particularly pointed out inthe claims.

Figure 1 isa side elevation of the operative parts of the toolsupporting and operating mechanism. Fig. 2 is an end elevation of thesame, and Fig. 3 is a plan view looking from above. Figs. 4, 5 and 6 arecorresponding views of a second and preferred form of the invention.Fig. 7 is a diagrammatic elevational view showing the operativemechanism as mounted in position on the machine frame, and Fig. 8 is adetail thereof.

1 is a hollow shaft mounted in suitable bearings and continuously drivenfrom any convenient source of power, as by means of a pulley 1*. Withinsaid hollow shaft and carried thereby is a relatively fixed rod orsupporting-member 2. This rod may be held in fixed position withrespect. to the frame of the machine by any suitable means, but isherein shown as provided upon its rearward extremity with a gear 3,which gear is arranged to mesh with asecondary gear or. rack 23* (Fig.7') adapted to be turned manna ally and to be fixed in either of twoadjusted positions for a purpose which will be hereinafter described.The forward end of said rod 2 is provided integrally or otherwise withan enlargement 4, such enlargement being slotted or bifurcated at itsouter extremity to provide opposed arms 5 and 6. Passing throughsuitably formed openings in said arms is a stub shaft or pintle pm 7said pin being provided with an en larged head at one extremity andbeing screw-threaded at its opposite extremity for reception of a locknut 8.- Pivotally supported upon said shaft or pin 7 is a rockabletool-holding head 9 adapted to vibrate in a vertical plane passingthrough the center of shaft 2. This tool-holdinghead 9 is provided witha pair of oppositely extending posts 110, and 11, said posts beingprovided with suitably formed extremities l2 and 13 for the reception oftool holders of the type usually employed in machines of this character.Projecting from the posts 10 and 11, and in the plane of vibration ofsaid head are a pair of bracket arms 14 and 15, said arms being spacedfrom the main portion of the head 9 to form openings 16 and 17therebetween. Fixed in alined open? ings in said brackets and in thehead and extending across said openings are a pair of fixed pins 18 and19, said pins forming the axes of rollers 20 and 21, the rollers hereindisclosed having the form of oblate spheroids, this specific form ofroller, however, not being essential as rollers" of any other suitableand desired form may be substituted therefor.

.Fixed upon the end of the shaft 1 to rotate therewith is a disk-member22, said disk-member being provided upon its face with a groove orrun-way 28. This groove or run-way, as may be seen from inspection ofFig. 3, is deeper at the part 25 than at the part 245 which isdiametrically opposite the same, the groove as thus described forming ineffect a face-cam of varying depth.

The support 4 is so located with respect to the shaft 1 and disk 22 thatthe rollers 20 and 21 engage with the bottom of the by reason of thetravel of the rollers '20 and 21 over the high and low parts of the camgroove 23, the head 4 carrying said rollers and the tool-holding postscarried thereby will be rapidly vibrated in a plane parallel to the axisof the shaft 1.

Byreason of the fact that the operative partsinthismachine areall'loca'ted closely adjacent the bearings and that no long or heavylever-members are necessary for securing the desired movement of thetoolcarrying parts, very little vibration in the machine frame with itsconsequent noise and wear isproduced, the machine as above con structedbeing almost noiseless in its operation,while at the same timeperforming its work well and efficiently.

The machine herein disclosed as above described is provided withoppositely extendingtool-carrying posts, and by reason of thearrangement described, embodying the gear 3 with means for turning thesame and lockingit in position, the relative arrangement of the posts 10and 11 may be reversed, thereby permitting the use, as is common inmachines of this general charac ter, ofseparate tools for operating uponthe shank and forepart of the shoe sole, the gear 3 and the describedconnections permitting reversal of the head as oftenas may be desired.

As an example of means for turning and locking the supporting-member 2reference may be had to F 7, wherein is shown a gear segment 3 fixed toa shaft 50e21tending through the frame and having a hand lever 51 uponits forward end, suchlever being provided with a locking pin 52 adaptedto engage either of a pair of suitably formed sockets 54: in the frame,whereby the lever 51 together with gear segment 3 may be locked'at willin either of the two desired positlons. While the locklng means theclosed is well adapted for use inthe present machine, it is to beunderstood that the invention is not limited thereto as any other andequlvalent mechanism may be substituted therefor. In the modificationshown in Figs. 4, 5 and 6 many of the parts cor upon the same; a theforked or bifurcated head carried upon said supportgo and G theoppositely disposed a ms of said forkedmember; the pintle pin or shaftand 8 the lockingnut for the same.

Mounted to rock upon said pintle pin is the vibrating tool-holding head9*, said head havingextending therefrom in opposite directionsthetool-carrying posts lO 'and 11. Upon the posts 10 and 11 is pivoted toescillate in a horizontal plane a disk or yoke memoer 30, saidyoke-member being provided with arms 31 and 32 having journal openings31, 32 therein adapted for pivotal mounting upon the posts. 10 and 11.The yoke-member 30 has formed upon its rearward face a groove 33 formingone element of a ball-race. Fixed upon the shaft 1 is a disk 22 havingformed therein a groove 34', said groove forming the complementalball-race element, the disk 22 being also provided with a flange 35inclosing the circular ing said ball-race 33. Inspection of Fig. (i willshow that the ball-race 3a is deeper at the part 25 than at the part524:, thus forming in effect a cam groove in the face of said disk.Between the ball-race elements 34: and is mounted a: continuous seriesof ball bearings 36, said bearings serving to transmit motion from therotating disk22 to the yoke-member 30. r

Upon rotation of the shaft 1 the race element Sd is rotated, causing thebearings held in the same to travel with relationto therespective raceelements 34 and 33, and by reason of the inclined arrangement of theraceelement 34, such rotation will cause a rocking movement of the yoke30 about its pivotal support. Asthe shallow portion of the groovepassesthe vertical plane, it will cause a rocking movement of yokeelement 30 together with head 9* about the pintle pin 7, thus producingthat movement of the tool holders necessary for the proper function ofthe machine. its the shallow portion of the groove, however, passes thehorizontal plane, a rocking movement of yoke 30 about the posts 10 and11 will be produced, this movement being an idle movement as far as thetools are concerned, its only function being to'prevent jamming of theball bearings in passing along the race which action would occur in thisform of the invention due to the employment of the continuous seriesofbearings unless some provision of this character were made.

It will be evident, therefore, that yoke 30 is given a Wabbling motionwhich may be considered as vibration in a plane which isconstantlyfrotating about the. cam axis or as vibrating inan infinitenumber of planes while it isso held. Vhen the tool holder is rotatedtolchange tools, its plane of vibraortionof the yoke-member 30 carrytionrotates similarly to that of the actuatin yoke 30.

Vhile the form shown in Figs. 4, 5 and 6 is a preferred form of theinvention, it is to be understood that the invention is not to belimited to the specific details of construction herein shown, but thatit is to be construed as covering all modifications and variations ofthe same within the province of mechanical skill, and as included in thescope of annexed claims.
